A newly disclosed privacy vulnerability in Apple’s Hide My Email feature can reportedly allow an attacker to uncover the real email address behind a generated alias. According to the researcher who found the bug, it was responsibly disclosed to Apple more than a year ago but remains unpatched, and independent testing has verified the issue.
addy.io offers a free tier if you’re looking for an alias provider/alternative.
Wanted to use it but couldn’t sign up bc it didnt know my domain. They sent an automatic email to which I should reply to, but I never got a confirmation. Yes, I replied with the same address I’ve signed up with. That was, however, months ago so I should give it another try.
I don’t use if with my own domain so I can’t speak for success with that. I’ve used them for a long time for my occasional alias needs, before they renamed from anonaddy iirc.
